It is the best choice for remote control, production, packaging, transportation, inspection, warehousing, and all kinds of equipment and product automated assembly lines.
①Full copper coil: Adopts high standard turn-to-turn electromagnetic coil with stable current, heat resistance, better heat dissipation, reliable suction, and long service life. ②LED indicator light: Adopts LED indicator light with long service life. Red indicates AC coil, green indicates DC coil. ③Contact material: Adopts silver oxide tin steel with silver layer thickness of 0.4mm. The contact is thickened to support large current. The moving contact sheet material is imported FCNP-C17200 copper, which is quenched with super elasticity and high frequency working control without overheating. ④Plastic buckle: Equipped with a locking function to make the relay more sturdy. It has a built-in label to mark the corresponding circuits. ⑤Adopts copper feet: The copper material enhances the contact conductivity and reduces the resistance value. The process of first plating and then punching and integrating with the mold ensures that the contact and foot position synchronize without deformation.
